Worldfairs Forum - Expositions Universelles et Spécialisées

Voici le petit train (électrique bien sûr) de l'Exposition

Are you kidding ?!!!
or you ignore the innovation presented in Expo2020
There are two different kinds of clean trains in Expo :
the train you show in Expo2020 in front of the USA Pavilion, called also ExpoExplorer, is an electric train, something almost usual now.
the REAL innovation is the other ExpoExplorer train : an AIR TRAIN : powered by compressed air !!!

For the Electric Expo Explorer, it's not a innovation, it is a means of transport.

For the Air Expo Explorer, nobody talks (no articles, no pictures) to it except the website that you mention, strange

Can it not work?

Do you have some pictures, and docs of this train
